How do I stop infatuation?

I had an infatuation with a celebrity (Selena Gomez) and it got really deep. It lasted for a half of a year and it got really bad where I would cry sometimes. I even changed what I wanted to be when I got older. Then it got worse and I believed I would not find someone as good as her and I fell into a quick and small depression. I researched how to stop it and all i had to do was distract myself if i would start to think about her. Also i got rid of my pictures of her and her songs and with some time, it went away. I still like her but it is just an attraction and not an infatuation.
